During July 2016, the containership fleet reached a landmark 20 million TEU in terms of aggregate capacity. To many it only seems like yesterday when the boxship fleet passed the 10 million TEU mark, back in April 2007. It took less than 10 years to double in capacity to reach the new milestone. Sprightly fleet growth indeed, but how rapid is it when compared to other parts of the world fleet?

Compound Crazy

Albert Einstein once called the impact of compound growth the ‘most powerful force in the universe’, and containership fleet capacity is a great example of this power. Total boxship capacity doubled from 5m TEU in size (in April 2001) to 10m TEU (in May 2007) in 6.2 years, and since then it has doubled in size again from 10m TEU to an astounding 20m TEU across just a further 9.3 years.

This rapid growth of the containership sector is a fairly well known story. In many respects the box sector is still a youthful part of the shipping world; since the inception of container shipping in the 1950s, the fleet has grown quickly from humble origins as trade has flourished. At the same time the fleet has upsized at a phenomenal rate. The average size of containerships in the fleet stood at 1,807 TEU in April 2001 and increased to 2,425 TEU in May 2007. Today, with behemoth boxships of over 19,000 TEU on the water, the average size of units in the fleet is 3,832 TEU, and the average size of those on order is even larger at 8,030 TEU.

Maturing Slowly

In contrast, some other shipping sectors can seem more ‘mature’, growing at a gentler rate. Tanker fleet capacity took almost 21 years to double to reach its current size of 540.9m dwt. In relative terms, the trade is indeed fairly mature, with average growth in volumes of 2.2% per annum over the last 20 years in combined crude and products trade. But interestingly, this is a sector now seeing rapid capacity growth, with an uptick in trade growth in recent years driving tanker ordering. In the last 19 months tanker fleet capacity has grown by 6.5%.

Bulk Bulge

However, the bulkcarrier fleet comfortably illustrates that the boxship sector has not been alone in experiencing rocketing growth. Although the vessels themselves may not have seen the same upsizing as boxships, bulker capacity expansion has been extraordinarily fast in recent times. Astonishingly, it took just 8.6 years from January 2008 to double to its current capacity of 784.1m dwt (though it had taken around 21 years before that to double previously). Nevertheless, bulker capacity expansion has slowed now, as dry bulk trade growth has hit the buffers.

Boom Time

So, the latest instance of a rapid doubling of fleet capacity is not a one-off. The explosion of boxship capacity has indeed been rapid, but in a world where shipbuilding output was hitting all-time highs not long ago, such growth has been a wider phenomenon. The overall world fleet has increased by 55% in dwt terms in the period since the onset of the global financial crisis in September 2008 alone. That’s a robust compound annual growth rate of 5.1%! Have a nice day, Einstein!
